This guy in Russia caused a little more than $100,000 in damage when he didn't think about lowering a bulldozer into a pit with a crane.

Things start out okay until the crane begins lowering the bulldozer lower than it should go. At that point the heavy equipment is just too much for the crane to take and it begins to lean forward. The guy jumps out just in time before both of them topple straight into the pit and crash.

We're guessing the guy lost his job and probably won't work in that business again.
